Abstract
The invention discloses a safety wire protection clamp comprising a hollow shell, wherein the hollow shell is longitudinally divided into two halves which are connected through a turnover part at the side part so as to be opened and closed along the longitudinal direction, the cavity in the shell is coaxial with the safety wire protection clamp, one end of the cavity is provided with an opening on the shell, an inward transverse bulge is arranged at the middle part of the cavity, and the space in the cavity around the bulge is larger than that of other parts. The invention adopting the technical scheme has simple structure and low cost, can be used for effectively wrapping up a tip of a lead, and prevents electric shock or short-circuit accident.
Description
Technical field
The present invention relates to the instrument that a kind of electrician uses, especially a kind of instrument of being insulated in the lead termination of being used for.
Background technology
Now, in electrician's operation, running into through regular meeting need be unsettled with lead termination useless.These lead terminations, some are arranged is uncharged, is charged but some are arranged.To such lead termination, if do not deal with, let alone unsettledly, can cause operating personnel's electric shock, perhaps serious accident such as wire short-circuiting even initiation fire.Generally being to adopt insulating tape that the lead termination is encased to the processing mode of these lead terminations in the prior art, is outside the metal part of lead termination can not be exposed to, thereby prevents to get an electric shock or the generation of short circuit.But if the time has been grown, insulating tape might wear out, and the glue on the adhesive plaster also might ftracture, if do not safeguard timely that the metal of lead termination partly still probably comes out, thereby causes the generation of peril.In addition,, be difficult to different lead terminations is identified, in follow-up work, also need in addition the lead termination to be distinguished, thereby increased workload because the insulating tape that is adopted when operation generally all is a color.
Summary of the invention
Technical problem to be solved by this invention provides a kind of safety wire protection clamp, can adopt very simple structure and cheap cost, can effectively wrap up the lead termination, avoids getting an electric shock or the generation of short circuit accident.
For solving the problems of the technologies described above, the technical scheme of safety wire protection clamp of the present invention is, comprise a hollow housing, the vertical dimidiation of described hollow housing, the two halves housing connects by a folding portion of side, make the two halves housing can longitudinally turn down opened/closed, cavity and described safety wire protection clamp in the described housing are coaxial, this cavity one end housing is provided with opening, described cavity middle part is provided with an inside transverse projections, and it is bigger than the void space of other parts to be positioned at described projection void space on every side.
The present invention adopts technique scheme, and it is simple in structure, and is with low cost, can effectively wrap up the lead termination, avoids getting an electric shock or the generation of short circuit accident.

Schematic diagram when Fig. 2 opens for safety wire protection clamp of the present invention.
Reference numeral is among the figure, 1,2. housing; 3. folding portion; 4. cavity; 5. opening; 6. projection; 7. the cavity around the projection; 8,9. buckling parts; 10,11. force sections; 12. through hole; 13. clamping part.
Embodiment
The invention discloses a kind of safety wire protection clamp, as depicted in figs. 1 and 2, comprise a hollow housing, the vertical dimidiation 1 of described hollow housing and 2, the two halves housing connects by a folding portion 3 of side, make the two halves housing can longitudinally turn down opened/closed, cavity 4 in the described housing is coaxial with described safety wire protection clamp, these cavity 4 one end housings are provided with opening 5, described cavity 4 middle parts are provided with an inside transverse projections 6, and it is bigger than the void space of other parts to be positioned at described projection 6 cavity 7 spaces on every side.
When practicality, described safety wire protection clamp can be opened, make lead be exposed to outer metal termination then and be wrapped in described transverse projections 6 outsides, thereby be contained in the void space 7 in transverse projections 6 outsides, the conductor part that is surrounded by insulated hull can be passed through cavity 4 and opening 5, then with described safety wire protection clamp closure, thereby make that originally being exposed to outer lead metal termination is wrapped in described safety wire protection clamp inside, and because lead has twined on the described transverse projections 6 again, safety wire protection clamp also is not easy to split away off from lead.
The opposite side that is positioned at respect to folding portion 3 on the described two halves housing is provided with the buckling parts that cooperatively interacts, in Fig. 2, housing 1 is provided with buckling parts 8, housing 2 is provided with buckling parts 9, cooperation by buckling parts 8 and 9, make to be fastened after the described two halves housing closure, avoid the metal termination of safety wire protection clamp inside to come out.Like this, described safety wire protection clamp can expose the lead termination owing to cracking takes place glue as prior art.
The opposite side that is positioned at respect to folding portion on the described two halves housing is provided with bossed force section, opens closed housing thereby be used to apply strength, staggers mutually in the position, force section on the described two halves housing.As shown in Figure 2, housing 1 is provided with force section 10, and housing 2 is provided with force section 11, and like this, the user can pull two force sections with finger easily, thereby opens closed housing.
The projection 6 of described cavity 4 inside is provided with the through hole 12 coaxial with described cavity.If lead is difficult for being wrapped on the projection 6, can also makes lead pass through hole 12, thereby safety wire protection clamp is wrapped on the lead termination.
Between described transverse projections 6 and described opening 5, be provided with inside clamping part 13 in the described cavity 4.After safety wire protection clamp parcel lead termination, this clamping part 13 can be clamped on the insulated hull of lead, makes that the installation of safety wire protection clamp is more firm.
Safety wire protection clamp of the present invention can be made of plastics, and can have good insulation property, also has good plasticity, and in light weight, and cost is low.
In sum, safety wire protection clamp of the present invention simple in structure, with low cost can effectively be wrapped up the lead termination, avoids getting an electric shock or the generation of short circuit accident.
